IDS4 — Brassica oleracea var. botrytis

Summary

BoIDS4 (also known as GGPS2, GGPPS4, GGPS5, IDS4) on cauliflower chromosome 8 encodes a prenyl diphosphate synthase, a member of the polyprenyl synthetase family. The enzyme possesses geranyltranstransferase, farnesyltranstransferase, and dimethylallyltransferase activities, and is annotated as an all-trans-nonaprenyl-diphosphate synthase (geranyl-diphosphate specific). BoIDS4 is associated with the biosynthesis of geranylgeranyl diphosphate, farnesyl diphosphate, and geranyl diphosphate, as well as with isoprenoid, terpenoid, carotenoid, plastoquinone, and ubiquinone anabolism. The gene is linked to responses to herbivores, insects, jasmonic acid, and salicylate. It is localized to plastids, chloroplast stroma and thylakoid membranes, the endoplasmic reticulum, and mitochondria. BoIDS4 is also linked to photosynthetic rate. Studies of related genes in other species connect the family to leaf shape, meristem identity, and photochemical quenching.
